THOMAS EL LUTNER, OF PHILADELPHIA, PENNSYLVANIA.

Lmm Patat No. 90,455, dated May 25, 1869.

IM'PRO'TED CRANE-XL2 FOR WAS-ONS.

The Schedule referred to in these Letters Patent and making part of the same.

axles for wagons, trdcks, 8m., whereby it is designed to provide such a construction ofthe same as will admit of more room between the vertical portions of the axle, without increasing the distance between the wheels, than is ai'orded by the present construction, as will be more fully described on reference to the accompanyng drawings, wherein- Figure 1 represents a side elevation of my improved axle, and

Figure 2 represents a section ofthe same.

Similar letters of reference indicate like parts.

Itis desirable to provide the greatest breadth for the load that may be within the limits of the total breadth of the wagon or truck, especially where it is desirable to set the wheels, so as to run on the rails of street-railroads, which are commonly slightly narrower than the wheels of trucks are desired to be.

And in the case of the employment of cranked-axle trucks, having the wheels within the limit ofthe breadth of the said rails, it is exceedingly difcult to make them wide enough for conveniently loading some kinds Of hogsheads, such as sugar or tobacco-hogsheads, without reducing the length of the hubs to such an extent as to weaken them.

To meet these diiculties, I propose to reduce the breadth Of the vertical portions a of the axles, and

correspondingl y increase it transversely, as represented at b, in fig. 2, whereby the distance c between't-he said vertical parts may he correspondingly increased, the said reduction being madeon the Outer sides of the vertical parts a, and curved, as represented at d, allowing the hubs, which may be correspondingly curved, to Work closely up to the said reduced and curved portion.

In axles for strong trucks, this arrangement permits an increase of space for the load of from twoto five inches, without lessening the length of the hubs.

Having thus described my invention,

I claim as new, and desire to secure by Lettersl Patent- Granked axles for wagons, having the vertical por-v tions a thereof reduced in the direction of the length of the axle, and widened correspondingly in the direction transversely to the said vertical parts, substantially as 'and for the purpose described.
